IPC: C04B18/08
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To effectively utilize sludge of flied ash containing free lime for aggregates for civil engineering works, etc., by adding fly ash to the sludge containing the free lime to remove water, curing and solidifying the obtained dehydrated cake and then grinding the solidified product. SOLUTION: This method for treating sludge comprises (1) the step of adding fly ash to the sludge containing free lime to hydrate the sludge, (2) the step of curing and solidifying the dehydrated cake produced in the dehydration step; and (3) the step of grinding the dehydrated cake treated in the curing step into a ballast-like product. This treatment method enables to produce coarse aggregates or fine aggregates from the sludge containing the free lime produced from steel production slag generated from a steel mill, and to utilize the fly ash generated from steel mills, coal thermoelectric power stations, etc., to prevent difficult treatments such as transportation, and dust pollution which is caused by the collapse and weathering of the coarse aggregates or the fine aggregates to fly the fine powder.

Abstract: PURPOSE:To prevent mixtue of a modulated component by generating a signal for compressing and expanding an original signal in prescribed methods relatively to the original signal, modulating a specified auxiliary signal by said signal, and then performing demodulation by removing an unnecessary part. CONSTITUTION:A signal generator 10 generates a signal f{A(t)}on the basis of which an original signal A(t) having 20kHz band width is compressed and expanded. An oscillator 11 sends an auxiliary signal g(t), e.g. a 60kHz rectangular wave signal. A device 12 imposes amplitude modulation upon the output of the generator 10 by the output of the oscillator 11.

Title: Lsi circuit
Inventor: KUBOTA KATSUHISA
IPC: H03K19/003
Filed: 1991-03-20
Abstract: PURPOSE:To obtain a LSI circuit in which a logic inversion fault due to alpha-ray irradiation hardly takes place by applying E-dot to the output of an output stage gate or forming a duplicate loop, thereby feeding back the result to an input stage gate respectively. CONSTITUTION:Emitters of transistors(TRs) Q13, Q14 are connected in common to form an E-dot circuit and a voltage at a common connecting point is fed back to a gate input section. The TRs Q11, Q12 are turned off and a '1' level signal is inputted to the bases of TRs Q13, Q14 of the next stage. Consequently, the TRs Q13, Q14 are turned on and emitters go both to a '1' level. Suppose that the TRs Q11, Q12 are irradiated with alpha-ray and the TR Q11 is turned on, then its collector output goes to a '0' level and the TR Q13 is changed from ON to OFF state. Since the ON-state of the other TR Q14 is kept, no output is changed. Thus, even when the TRs of the pre-stage is inverted due to alpha-ray irradiation, the output is unchanged and the occurrence of a logic inversion fault is prevented.

Filed: 1979-05-10
Abstract: PURPOSE:To easily evaluate quantitatively a semiconductor wafer without contamination by irradiating laser light to strained surface and measuring the reflected light as a method of evaluating the strain formed at the wafer for absorbing the infinitesimal fault in the wafer. CONSTITUTION:Laser light 2 from an Ar iron laser tube 1 is irradiated through a half mirror 7 on the strained surface of a semiconductor wafer 3 formed with a strain for absorbing infinitesimal fault on the back surface. Since the light 2 is linearly polarized at this time, it is incident at 1 deg. 15' to eliminate the adverse affect thereof, and the stability of the light 2 is confirmed by a monitor 8 using the reflected light from the mirror 7. Then, the reflected light 4 from the strained surface is received by a solar battery 5, the output from the battery 5 is measured by an ammeter 6 to detect the strained state. Thus, the current value obtained from the ammeter 6 is preferably responded to the number of the faults on the laminate showing the degree of the strain to enable evaluation of the strain by the current value.

Title: Lighting system for elevator car
Inventor: TERASAKI MASAYUKI
IPC: B66B1/16
Filed: 1995-03-16
Abstract: PURPOSE: To maintain energy-saving effect while prolonging the service life of an illuminating lamp in a car. CONSTITUTION: In a normal operating state, an illuminating lamp 1 in an elevator car is lighted to full luminance by a current control circuit 2a. When an elevator stoppage detecting circuit 4 detects the stoppage state of an elevator, a luminance suppressing lighting current reference is supplied to the current control circuit 2a from a luminance suppressing lighting current reference circuit 2c so as to restrict a current fed to the illuminating lamp 1, thus dimming the luminance of the illuminating lamp 1 only by a fixed degree. Accordingly, at the time of detecting the stoppage state of the elevator, the illuminating lamp 1 in the car is not put out but dimmed so as to economize demand and to reduce the frequency of putting on and out the light. As a result, the service life of the illuminating lamp 1 is prolonged, and energy-saving effect is attained.

IPC: G06F12/02
Filed: 1984-03-26
Abstract: PURPOSE:To facilitate change of an address and to simplify configulation by utilizing a P-ROM or an EP-ROM to constitute an address decoder. CONSTITUTION:Address signals A-13-15 of a mu-CPU 1 are made to correspond to A0-A2 of ROM2 for an address decoder respectively. Consequently, data of 8 bits in the ROM2 for the address decoder are selected and outputted corresponding to the change of address signals A-13-A-15. Supposing that all of address signals, from A-13 to A-15, are 0, the first data area 000- is selected, and corresponding data 00000001 are outputted. As only the least significant bit (LSB) of this output is ''1'', the output signal is address decode, whose output goes to ''1'' only in address space of 0000-1FFF of address area of actual mu-CPU. Giving this to a RAM3, the RAM area can be made to 0000-1FFF.
